1 Claim.

This invention relates to thrust collars employed on shafting and hasfor the primary object, the provision of an efficient and inexpensivedevice of this character which may be easily 5 mounted on a shaftbetween shaft bearings for limiting shaft thrusts and which may beeasily and quickly adjusted to compensate for wear as the latter occurs.

With these and other objects in view, the invention consists in certainnovel features of construction, combination and arrangement of parts tobe hereinafter more fully described and claimed.

For a complete understanding of my invenl5 tion, reference is to be hadto the following description and accompanying drawings, in which Figure1 is a side elevation illustrating a thrust collar constructed inaccordance with my invention.

Figure 2 is an edge elevation, partly in section, illustrating thedevice.

Figure 3 is a View similar to Figure 2 showing the collar adjustedthrough the use of shims.

Figure 4 is a plan View illustrating companion sections of the collarand the connecting means between said sections.

Figure 5 is a View similar to Figure 4 showing shims in position foradjusting the companion sections of the collars relative to each other.

39 Figure 6 is a plan view illustrating one of the sections of theshims.

Figure '7 is an edge view illustrating one of the sections of the shims.

Referring in detail to the drawings, the numeral I indicates in entiretythe thrust collar having side bearing faces II. The collar presents acircular opening I2 to receive a shaft. It is to be understood that thiscollar operates on the shaft between bearings (not shown) of the Wshaft. The securing of the collar on the shaft can be accomplished inany well known manner.

The collar is composed of a pair of one-half sections A and B and eachsection includes companion semicircular shaped members I3 and I4arranged in abutting engagement. The member I3 has secured therein pinsI which fit in sockets I6 formed in the member I4. These pins permiteasy separation of the members when desired and normally preventrotation of the members relative to each other. Formed on the ends ofthe members are cars or flanges I! having slots I8 to receive fastenersI9 each in the form of a bolt and nut. The ears or flanges are soarranged that they will overlap when the sections A and B are broughttogether permitting the slots to align so that the fasteners I9 may beeasily applied or removed. The slots I8 also permit the members of eachsection to be adjusted towards and from each other so that as wearoccurs on the faces II shims may be employed between said members fortaking up wear. The shims are indicated by the character 2I and thethicknesses may vary to meet with different operating conditions. Eachshim 2| consists of semicircular shaped sections 22, each section havingopenings 23 to permit the pins of the companion members to passtherethrough when the shim section is arranged between the members. Thepins extending through the shims prevent the latter from working outfrom between the members of the collar and will permit the shims to beeasily and quickly applied and removed from a collar as desired.

In the Figure 3 the members of the collar are shown adjusted to the useof a pair of shims and any number of shims may be employed as long asthe pins of one of the members will extend into the sockets of thecompanion member.

The collar described in detail and shown in the drawings will limitlateral thrust of the shaft to a predetermined amount for which thecollar is set for on the shaft and is easily and quickly adjustable tocompensate for wear caused by taking up the thrust. With limiting of thethrust excess wear and subsequent repairs are reduced to a minimum.

It is beleived that the foregoing description, when taken in connectionwith the drawings will fully set forth the construction and advantagesof the present invention to those skilled in the art to which such adevice relates, so that further detailed description will not berequired.

Having described the invention, what I claim 1s:

A thrust collar comprising an annular body composed of a pair ofone-half sections and each section including companion semicircularshaped members arranged opposite to each other, certain of said membershaving sockets, pins formed on the companion members to the membershaving the sockets and fitting in said sockets, sectional shims havingopenings to receive said pins and secured thereby between the companionmembers, flanges formed on the ends of the members and having slots, theflanges of the members of one section adapted to overlap with theflanges of the members of the other section with the slots thereof inalignment, and fasteners extending through the slots.
